1 asprin'kler which is adapted to be connected ina' line ofhose'orpipeand to seat onthe ground so as to form a fountain'whereby awater spray may be dire'cted'separately from the nozzle and spreadlaterally therefrom soas to irrigate a wide area of ground from adjacentthe nozzle to points remote therefrom, and which nozzle is soconstructed that a plurality of. sprinklers may be readily connected inseries in a conduit.

A further object is to provide a sprinkler of the type specified whichis simple in construction and which may be manufactured at such low costthat it may be marketed at a comparatively low price. v

I The invention is illustrated in the accompanying drawings, in whichFigure 1 is a plan view of the device.

Figure 2 is a view of same in side elevat-ion.

Figure 3 is a view in vertical section as seen on the line 85 ofFigure2. I

Figures 4, 5 and 6 are plan views of demountable and interchangeableplates employed in the sprinkler. V

Figure 7 is a plan view illustrating the manner in which the sprinkleris arranged in series in a conduit.

More specifically, 8 indicates the body of the sprinkler which is hereshown as being in the form of a T-coupling comprising a pair of alignedintegral nipples 9 and 10 from which projects an open ended tube 11formed intermediate the ends of the nipples and extending at rightangles thereto; the body being formed with a main passage'A extendingthrough the nipples and communicating with a vertical passage B in thetube 11. The nipples 9 and 10 are here shown as externally threaded andadapted to be con nected to lengths of conduits 12 which may compriseflexible hose or metallic pipe, as may be expedient.

The tube 11 is externally threaded and is formed at its outer end withan inturned flange 13 to provide a seat for a gasket 14. Seating on thegasket 14: is a plate 15, here shown in the form of a disk, and. which.

plate may be formed with a series of perforations 16 arranged atsuitable intervals apart throughout the central area thereof, as

shown in'Figure 4, o'rmay provided with j rater FA ENE? BF EEperforations 17 arranged throughout a portion of the area'of the centralpart 10f the disk or plate a's'shown in Figure 5, or it may beimperforate as shown Figure 6. The plate 15 is demountably secured inplace by an aperturedf'cap 18 which is screwed on the tube 11 andisformedwith anjinturned j flange: 19 rormn g h margin; of an opening 20in the top ofthe cap and which flangeis adapted to seat on the margin ofthe plate 15 as shown in Figure 3 whereby the central portion of theplate 15 is exposed through.

the opening 20 in the cap. The central per-' forated portion of theplate is preferably bowed outwardly so as to extend into the opening 20.The passage B with the cap 18 and the perforated plate 15 constitute aspray nozzle. m j

Extending at a slight downward angle from thehorizontal from theopposite sides of the body 8 intermediate the ends and adjacent theunderside thereof is a pair of U- shaped wires 21 and 22 theterminations of the side members of which are embedded in the materialof which the body Sis formed; the wires 21 and 22 extending downwardlyat a slight incline from their intersection with the body 8 and servingas .foot members whereby the sprinkler may be seated on a substantiallyflat surface as on the j ground and positioned with the nozzle extending vertically; the wire T0013. members having such lateral spreadas to hold the nozzle against tilting in event the ground on which thesprinkler is placed be slightly uneven, and by virtue of the footmembers being long and narrow they are adapted to be pressed into theground where necessary in order to level the sprinkler should occa sionso require. I

In the application of the invention a series of any suitable number ofsprinklers are connected together by conduits 12 of suitable lengths tospace the adjacent sprinklers the desired distance apart. A line ofcon.- duit may thus be formed of any desired length with any suitablenumber of sprink lers interposed therein, being ordinarily portable sothat it may be readily shifted from place to place and which by reason.of

thelateral projections afforded by the foot members 21 and 22 may beeasily positioned with the nozzles extending upwardly. The

conduit thus formed, being connected to a source of water supply, waterwill be delivp in the sprinkler nozzle.

ered successively to each of the sprinklers in the. line and will bedischarged therefrom according to the character of plate 15-placed As ameans for impartlng an upward tendency to the flow of water through thepassage A so as to direct it into the passage I B, the bottom wall ofthe passage A is formed at a point beneath the passage B with transverseribs 23 having inclined faces adapted to direct upwardly a-portion ofthe Water flowing through the passage A, which ribs, however, arerounded on top and are shallow so as not to materially impede the flowof Water from one nipple to the other. I claim r A sprinkler of theclass described'comprising a body portion constructed as a unit ofsubstantially T-shape, and consisting of a pair of aligned nipples, forconnection in a water line, an open topped.

branch extension formed at an angle to the nlpples and for connectionwith a sprinkler head, and a support; formed 8X:

ject from each side of thebody and at-an angle downwardly and outwardlyther efrom, the botttom of said SUPPOIblYlDg in substantially thesame'plane as the free ends of said foot members. I
